Ok... i inherited a couple of mailservers (non-toaster) which do 100k+ mail
each day each. The setup is similar enough and I've made a couple of
changes to tcp.smtp to limit the max envrcpt's and failed chkuser to 3, but
I'm having a brain cramp on another issue related to chkuser.
Using one of the servers as an example, here is what is happening:
Mail arrives and then attempts to bounce to an invalid sender and stays in
the queue for 7 days (i know how to change the days). What is bad is the
queue is full of "Subject: failure notice" messages which I then have to
clear out or it gets VERY large (hit 20k messages earlier this week). Since
I can tell from the logs that chkuser is running, what am I forgetting to do
to stop these from even being scanned.
Output from chkuser:
2006-05-05 16:49:15.161634500 CHKUSER rejected rcpt: from
<[EMAIL PROTECTED]::> remote <mail.sendingserver.com:unknown:1.1.1.123>
rcpt <[EMAIL PROTECTED]> : not existing recipient
Every time I've built a server it's automatically blocked when it arrived,
before accepting it (thus no simscan is called)... allowing the messages to
be scanned and then try to reject is silly (and a waste of resources).
Qmail-smtpd (i think it's this and tcpserver )? I doubt simscan, but I'll
post it's setting as well.

Oh, here's one of the .qmail-default files (there are settings I could try
here, but doubt that is what is needed):
| /home/vpopmail/bin/vdelivermail '' bounce-no-mailbox
and all the domains still use vpasswd (I'll convert these at some point).

So what am i forgetting? Other than saying ..."good luck" give me some
ideas. To many things going on and I feel like there is something I should
remember (lack of sleep does that).
